I'm pretty sure the digitizer and the LCD are glued together with OCA on the 3rd generation iPad mini... separating/replacing them requires the equipment that is used for iPhones. You can't use LOCA glue in place of OCA because apple didn't think it was a good idea to seal the backlight to the LCD. The iPad mini and the iPad air 2nd Gen are repaired the same way, which is different than the previous versions of ipads. Please correct me if I'm wrong
